Re: [9fans] Flash Video

I don't know of any open source implementations of Flash Player. The
software on each platform and for each browser seems to be (c) Adobe and
closed source. Does an open source implementation, however incomplete,
exist?

Videos embedded in SWF files are encoded in Sorenson's MPEG-4 profile.
